Electromagnetic Voltage Transformer Ratio and Polarity Tester, Electromagnetic Transformer Ratio Tester, Electromagnetic Transformer Polarity Tester

DGCT-SThe Electromagnetic Voltage Transformer Ratio and Polarity Tester, also known as the Electromagnetic Transformer Ratio Tester and Electromagnetic Transformer Polarity Tester, is a specialized transformer ratio and polarity testing instrument used for on-site ratio check tests during transformer handover and after winding replacement. The Electromagnetic Voltage Transformer Ratio and Polarity Tester supports the following standards:GB/T20840.5-2013、JB/T5356-199。

According toJJG313-94"Current Transformer for Measurement"JJG313-93The "Voltage Transformer for Measurement" requires on-site ratio check and test to be conducted during transformer handover and after the replacement of the winding.

       The conventional method for checking the ratio of regular transformers is the current method, which, in principle, is an easily understandable and feasible check. However, as the system capacity increases, the primary current of the current transformer becomes increasingly larger, reaching tens of thousands of amperes.;It is already challenging to increase the current on-site to hundreds of amperes, and it is nearly impossible to reach thousands or tens of thousands of amperes. Moreover, due to their large size and weight, which can be hundreds of kilograms or even tons, on-site use becomes even more difficult. Employing the small current method would significantly increase the error in the current transformer due to the influence of magnetic sensitivity, linearity, impedance, and leakage reactance, thus rendering the ratio check meaningless.

       The electromagnetic voltage transformer ratio polarity tester is compact, lightweight, features a wide measurement range, and is easy to carry, making it an increasingly essential tool for transformer testing work, particularly suitable for on-site current transformer ratio testing.DGCT-S The Electromagnetic Voltage Transformer Ratio and Polarization Tester is a summary of our company's domestic and international transformer characteristics.,Developed using the latest research theories and findings, in alignment with on-site application requirements.
